Q1. A force does +150 J of work when it acts on a moving object and its direction is in the identical direction as the object's displacement. How much work does this force do while the angle between it and the object's displacement is 54°?

Q2. If a system in equilibrium with two masses m1 and m2 are placed at distances d1 and d2 from the fulcrum, then f1 d1= f2 d2. Is this the same as saying that m1 d1= m2 d2? Give details.
